The species is
communal, forming communal nests. A typical group consists of a dominant male,
one or more younger males and several females. They build large nests on the
ground made of leaves, other combustible material and earth, 1 to 1.5 metres
high (3-4.5 ft) and up to 4 m (13 ft) across. The eggs are
hatched by the heat of the composting mound which is tended only by the males
who regulate the temperature by adding or removing material in an effort to
maintain the temperature of the mound in the 33–35°C (91-95°F) incubation
temperature range
